No. 81,427 Claimspriority, application Germany Sept. 5, 1957 Claims. (Cl. 66-54) Thepresent invention relates to adjusting and indicating devices for thecams of a circular knitting machine, and more particularly to anarrangement in which at each station of the circular knitting machine, afirst adjusting and indicating device is located on the cam box foradjusting the position of the raising and stitch cams, and forindicating the amount of displacement, and a second adjusting device islocated on the dial cap for adjusting the position of the dial cam, andfor indicating the displacement of the same.

The present application is a continuation-in-part application of mycopending application Serial No. 758,240,

led on September 2, 1958, now abandoned.

The present invention is concerned with an improvement of a circularknitting machine of the type including a set of cylinder needlesarranged on the needle cylinder, and a set of dial needles arranged on adial plate in horizontal positions and cooperating with the cylinderneedles. A dial cam is provided for advancing and retracting the dialneedles, and a cylinder cam is provided on the cam box of the machinefor raising and lowering the cylinder needles during rotation of theneedle cylinder with the dial plate.

It is desirable to accurately adjust the dial cam means and cylinder cammeans, and adjusting means are provided for this purpose.

In accordance with the present invention, a pair of adjusting andindicating devices is provided at each knitting station of the circularknitting machine, one adjusting device being provided for adjusting theradial position of the dial cam means, and the other adjusting devicebeing provided for adjusting the position of the cylinder cam means,which include a raising cam and a stitch cam.

It is one object of the present invention to provide the adjustingdevices with indicating means which face in the same direction so thatthey can be simultaneously in spected by the operator.

Another object of the present invention is to provide adjusting andindicating devices for the above explained purpose, which include firstindicating means for indicating unit distances of the cam adjustments,and second indicating means for indicating fractions of the distanceunits.

Another object of the present invention is to provide such first andsecond indicating means on both adjusting devices at each knittingstation, and to arrange all four indicating means to face in the samedirection for simultaneous inspection by the operator.

Since adjusting devices are arranged at each knitting station of themachine spaced in circumferential direction from each other, it is alsoan object of the present invention to facilitate the inspection of theadjusting devices by the operator by providing all adjusting deviceswith indicating means which face outwardly.

With these objects in view, one embodiment of the present inventionrelates to a circular knitting machine and comprises first and secondadjusting devices respectively connected to the dial cam means and thecylinder cam means of the knitting machine for respectively adjustingthe position of the respective cam means. A pair of first and secondadjusting devices is located at each knitting station in a radial planepassing through the main axis of the machine, and the indicating meansof the two adjusting devices at each station face in the same directionfor simultaneous inspection.

Preferably, each adjusting device has first and second indicating meansfor respectively indicating distance units and fractions of distanceunits through which the respective cam means are displaced, or the firstindicating means indicates degrees, and the second indicating meansindicates full turns of the knob by which the device is manuallycontrolled.

In the preferred embodiment of the present invention, one adjustingdevice is mounted on the dial cap, and has an operating knob, and a pairof indicating scales turnable about horizontal axes extending in radialdirection of the machine. The other adjusting device is mounted on thecam box, and has a knob turnable about a vertical axis, and first andsecond cylindrical indicating scales turnable about the vertical axisand being visible through indicator windows located in a vertical planeparallel to the vertical plane in which the indicating means of theadjusting device on the dial cap are located. The vertical scales of alladjusting devices are located in an imaginary vertical cylinder havingits axis coinciding with the axis of the machine, so that the operator,walking around the machine, can successively inspect all indicatingmeans at a glance.

The novel features which are considered as characteristic for theinvention are set forth in particular in the appended claims. Theinvention itself, however, both as to its construction and its method ofoperation, together with additional objects and advantages thereof, willbe best understood from the following description of specificembodiments when read in connection with the accompanying drawings, inwhich:

FIG. 1 is a fragmentary axial sectional view illustrating the parts of acircular knitting machine to which the present invention is applied;

FIG. 2 is a fragmentary horizontal sectional view taken on line 22 inFIG. 1;

FIG. 3 is a fragmentary vertical sectional view on an enlarged scaleshowing an adjusting device mounted on the cam box of the machine, andtaken on lines 33 in FIGS. 2 and 3a;

FIG. 3a is a fragmentary horizontal sectional view taken on line 3a3a inFIG. 3;

FIG. 4 is a front elevation of the adjusting device shown in FIG. 3 asviewed in the direction of the arrow 4 in FIG. 3;

FIG. 5 is a vertical sectional view on an enlarged scale illustrating anadjusting device mounted on the dial cap of the knitting machine; and

FIG. 6 is a fragmentary front elevation of the adjusting device shown inFIG. 5.

Referring now to the drawings, and particularly to FIGS. 1 and 2, aneedle cylinder 36 has on its outer cylindrical surface axiallyextending grooves in which the cylinder needles are guided for movementin vertical direction. Each cylinder needle has a butt 31a, and a hookand latch at its upper end for catching yarn supplied by feeding means,not shown. The dial plate or ring 32 has a horizontal top surface formedwith radial grooves in which the dial needles 33 are guided for movementbetween advanced and retracted positions so as to cooperate with thecylinder needles 31. The dial needles 33 have butts 33a. The dial plate32 and the needle cylinder 30 turn about a common vertical main axis sothat the needles 31 move relative to the stationary annular cam box 38,and the dial needles 33 move relative to the stationary dial cap 46.

It will be understood that a plurality of yarn feeding means arearranged around the circumference of the machine, and each locationwhere a feeding means is provided, is considered a knitting station.illustrate one of the knitting stations.

At each knitting station, cylinder cam means including a stitch cam 34aand the raising cam 3419 are provided which together form a cam trackfor receiving the butts 31a of the cylinder needles. Dial cam means aremounted on the dial cap 46, and include an inner cam 42a, and an outercam 42b. Cams 42a and 42b together form a cam track in which the butts33a of the dial needles are guided. Since the cylinder needles 31 anddial needles 33 rotate with the needle cylinder, while the cam means arestationary, the needles will be moved in longitudinal direction intocooperating positions for forming a knitted fabric.

In order to determine the degree to which the dial needles are advanced,and the height to which the cylinder needles are raised, the cylindercam means and dial cam means are adjustable.

The raising cam 34b and the stitch cam 34a are both secured by screws 36to a carrier which includes a plate 35 slidably mounted in a verticalchannel in the inner surface 38a, of the cam box 38, and a cylindricalrod 37 having a flattened face 37a abutting the rear face of plate 35.Screws 41 secure plate 35 to rod 37. A screw 39 is threaded into the cambox 38, and a spring 40 located in a recess 37b of rod 37 abuts screw 39and urges the carrier 35, 37, together with the cam means 34a, 34b inupward direction until the upper end face of the carrier rod 37 abutsthe bottom face of a member of the adjusting means 190. As will bedescribed hereinafter in greater detail, turning of the knob 1 of theadjusting means 100 will result in downward or upward movement of member5, so that the position of the carrier and of the cylinder cams can beadjusted.

The dial cams 42a and 42b are secured by screws 43 to a carrier 44slidably guided in a channel 45 of the dial cap 46 for radial movement.A screw 47 has a threaded portion threaded into carrier plate 44 to movewith the same. The stem of screw 47 is located in an elongated slot 43which permits radial movement of screw 47, but confines the same incircumferential direction of the dial cap 46. A spring 49 is located inrecess 50 of dial cap 46, and urges screw 47, and thereby carrier 44 andearns 42a and 42b outwardly in radial direction until screw 47 abuts athreaded bolt 13 of an adjusting means 51 provided with ,a turnable knob12a. Turning of knob 12a will effect axial movement of the threaded bolt13 for shifting cam means 42a, 42b against the action of spring 49, aswill be described hereinafter in greater detail with reference to FIGS.5 and 6.

Referring now to FIGS. 3, 3a and 4, which illustrate the adjusting andindicating device a bolt 2 has a first threaded portion 2a tightlyscrewed into a bushing 2 which is pressed into a corresponding bore inthe cam box 38 so that bolt 2 is not turnable. Bolt 2 has a secondthreaded portion 2e, another stepped portion 20, and a journal portion2b provided with a threaded recess into which a screw 2d is threaded.

A turnable member 3 is mounted for turning movement on the stationaryjournal portion 2b, and includes a bearing sleeve 3a with a flangeabutting the stepped portion 20, a cylindrical ring 4, and a knob 1.Ring 4 is secured to the flange of sleeve 3a by a press fit, or bytransverse screw passing through ring 4 into a threaded bore n theperiphery of the flange of sleeve 3. The screw is not visible in FIG. 3.A pin 1a secures the knob 1 against turning movement on the bearingportion 3a of the turnable member 3, and is held in place by the head ofscrew 2d. A turnable threaded member 5 engages the threaded portion 2eof the stationary bolt 2, and has on the outside thereof axiallyextending guide projections cooperating with matching axially extendingguideways in the inner cylindrical surface of the cylindrical ring 4.Consequently, members 1, 3, 4 and 5 are connected for turning movement,but member 5 will move in axial di- FIGS. 1 and 2 i rection when beingturned on the threaded portion 26. As best seen in FIGS. 1 and 2, thebottom face 5a of member 5 abuts the end face of the carrier rod 37, sothat the carrier 35, 37 will be shifted in vertical direction when knob1 is turned.

A pin 10 is urged by spring 10a against the bottom face 5a of member 5,and pin 10 is disposed at a diametrically opposite point in relation tocarrier bolt 37 in order to prevent binding of the threaded part 5 dueto the resistance of carrier rod 37 on one side of member 5.

A stationary casing member 6 has an annular part surrounding the bearingsleeve 3a, and a cylindrical casing part 6c which extends to knob 1 andinto a matching recess in the top face of the cam box 38. A pin 9 ispressed into a bore of the cam box, and projects into a correspondingopening in the cylindrical casing portion 6c so that casing member 6 isprevented from turning movement.

The casing portion 6c has windows 61 and 62 arranged above each otherand being located in a vertical plane tangential to the cylindricalcasing 60, and to an imaginary cylinder having its vertical axiscoinciding with the main axis about which the needle cylinder 30 and thedial ring 32 turn. An adjusting device is disposed at each knittingstation of the circular knitting machine, so that all windows 61, 62 ofall adjusting devices 100 face outwardly. A scale C is provided on theouter cylindrical surface of ring 4 so that the numbers of scale Cconsecutively appear in window 62 when knob 1 is turned.

An indicator ring 6a is mounted in a matching circular recess of member6, and has a set of upwardly projecting teeth or pins 612 arranged in acircle. The outer cylindrical face of indicator ring 6a has acylindrical scale D which is located under the window 61 so that thenumbers of scale D successively appear in window 61 when indicator ring6a turns.

Carry-over means connect the turnable member 3, 4 with the indicatorring 6a to effect a stepwise movement of indicator ring 6a after eachfull revolution of turnable member '3, 4 together with turnable member5.

The carry-over means include a pinion 8 mounted for turning movement ona pin 7 which has a portion secured to the annular member 6. Pinion 8has teeth 8a longer in axial direction, and teeth 81] shorter in axialdirection which are alternately arranged. Knob 1 has an innercylindrical surface lb on which a pair of longer teeth 8a slides in theposition of FIG. 3a during turning movement of knob 1. The shorter teeth8b are shorter in axial direction so that they do not extend into theregion of the recess having the circular surface 112.

The circular surface 112 has a single recess 1b, and a pair of pins 1elocated on opposite sides of recess 1b, but extending into the region ofthe shorter teeth 8!).

When knob 1 is turned, a pair of teeth 8a will slide on the innercircular surface 1b until the leading pin 1e engages the shorter tooth8b located between the respective teeth 8a. Pinion 8 will start turningand the trailing longer tooth 8a will turn to a position passing withits upper part into the single recess 1b. Further turning of knob l willresult in further turning of pinion 8 until the respective tooth 8apasses out of recess 1b and is now the leading tooth sliding on theinner surface 1b, while the next following tooth 8a trails and alsoslides on the inner surface 111. In this position, turning of knob 1 canbe continued for a complete revolution While pinion 8 is prevented fromangular displacement by the pair of longer teeth 8:: which slide on theinner surface 1b of knob 1, until the pins 1e and the recess 1b againbecome effective.

The shorter teeth 8b of pinion 8 mesh with the pins 6b of the indicatorring 6a. Consequently, ring 6a is turned one step every time the pinion8 is turned one step, so that the next following indicia of the scale Dappears in window 61.

As a result, scale D will indicate in window 61 complete revolutions ofknob 1, which preferably corresponds to distance units, for examplemillimeters of carrier 35, 37, and of the cams 34a and 34b. Scale C willindicate fractions of the distance units, or turning angles of knob 1.

The adjusting and indicating device 51 for the dial cams is shown inFIGS. and 6. A bushing 18 has a threaded portion 18a tightly screwedinto the dial cap 46. The threaded bolt 13 threadedly engages an innerthread 18b on bolt 13 so that turning of bolt 13 will result in axialdisplacement of screw 47 which is connected to carrier 44 of dial cams42a, 421;. As explained above, a spring 49 urges screw 47 and therebythe dial cams against the end face of bolt 18.

A knob 12a is secured by a screw 12b to a head portion of bolt 13, andan annular part 12 is secured to the head portion 13a and to knob 12afor turning movement therewith annular member 12 is turnable in a recessin a casing 52, and also surrounds a cylindrical portion of bushing 18.The end face of knob 12a has a circular scale E, as best seen in FIG. 6.

A single pin 15 is secured to the turnable member 12 and cooperates withthe teeth 11a of a pinion 11 which is turnably mounted on a pin 17threadedly secured to a portion casing member 52a of the casing 52. Theend face of pinion 11 is covered by a cover plate 14 secured to pin 17by a screw 15. Cover plate 14 has a window 140 through which a circularscale F on the end face of pinion 11 can be inspected.

When knob 12a is turned, bolt 13 is axially displaced and shifts carrier44 and dial cam means 42a and 42b in radial direction against the actionof spring 49. The angular position of the turnable member 12, 12a, 13 isindicated by the scale E, the valid indicia being the highest on thescale, as shown in FIG. 6, and being indicated by pointer mark 14b oncover plate 14.

After each revolution of knob 12a, pin 16 shifts pinion 11 one step sothat another indicia of scale F appears in window 14a to indicate onecomplete revolution of knob 12a, corresponding to a distance unit ofradial adjustment of cams 42a and 42b. Scale B -will indicate fractionsof the respective distance unit, or angle-s through which knob 12a hasbeen turned.

Scales F and E are located in parallel vertical planes which aretangential to an imaginary vertical cylinder having its axis coincidingwith the vertical axis of the knitting machine.

Referring again to FIG. 1, it will be seen that the scales C, D, E and Fall face in the same direction, and are located in parallel verticalplanes. Consequently, the operator can read the scale indicia E of thefirst indicating means, and the scale F of the second indicating meansof the adjusting device 51 at the same time he reads the scale indicia Cof the first indicating means, and the scale indicia D of the secondindicating means of adjusting device 100.

While in the adjusting device 109, the teeth 8a of pinion 8 cooperatewith the inner surface 112 to prevent undesired turning movement ofpinion 8, pinion 11 in the adjusting device 51 is held in position bythe friction exerted by cover plate 14 on the end face of piston 11.

It will be understood that each of the elements described above, or twoor more together, may also find a useful application in other types ofcircular knitting machines including adjustable cam means differing fromthe types described above.

While the invention has been illustrated and described as embodied in anadjusting and indicating apparatus for the dial cams and cylinder camsof a circular knitting machine and having all scales arranged in animaginary vertical cylinder for easy observation by the operator, it isnot intended to be limited to the details shown, since variousmodifications and structural changes may be made without departing inany way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist ofthe present invention that others can by applying current knowledgereadily adapt it for various applications without omitting featuresthat, from the standpoint of prior art, fairly constitute essentialcharacteristics of the generic or specific aspects of this invenventionand, therefore, adaptations should and are intended to be comprehendedwithin the meaning and range of equivalence of the following claims.
